Two San Francisco supervisors want to divide Muni’s parent agency into two departments.

Concerned with The City’s allegedly mismanaged transit policies, supervisors Aaron Peskin and Ahsha Safai have told stakeholders they plan introduce a June 2018 ballot measure that would split the San Francisco Municipal Transportation Agency, which manages Muni as well as San Francisco’s streets, stoplights, parking and curb colors.

Under the proposal, one agency would handle just Muni, and the other would handle San Francisco’s parking and streets, sources with knowledge of the measure told the San Francisco Examiner.

“A proposal to split back apart parking and traffic management from Muni, I think, would be a big step backwards,” said SFMTA Director of Transportation Ed Reiskin on Tuesday. Reiskin clarified that while he had not seen the ballot language, he is aware of the measure.

The proposal would also allow supervisors to make appointments to the SFMTA’s seven-member Board of Directors. Right now, directors are only appointed by the mayor.

Peskin and Safai have approached stakeholders with the ballot measure over the last week, and discussed introducing it as an amendment to The City’s charter at next Tuesday’s Board of Supervisors meeting, according to sources with knowledge of the measure.
